Cometic MLS cylinder head gasket for Pontiac 400/428/455 V8 applications, specified at a compressed thickness of 0.051 in with a 4.300 in bore. It features embossed stainless outer layers coated with Viton and a variable uncoated shim to match thickness needs. MLS construction rebounds and resists corrosion, providing reliable sealing without sealants. Appropriate for aluminum-to-aluminum or aluminum-to-iron head/block pairings, it requires less clamp load and helps keep bore distortion to a minimum.
